Description

Technical Field

[0001] The invention belongs to the technical field of camping vehicles, and in particular relates to a camping vehicle frame with a small folding volume and a camping vehicle. Background Art

[0002] At present, more and more people like to go out for activities such as camping or picnics. When camping outdoors, campers are often needed to transport items. Traditional campers are large in size and take up a lot of space in the trunk of a vehicle, which is inconvenient to carry. Therefore, some foldable campers have appeared in the prior art. The frame of the camper in the prior art can only be folded once, resulting in the camper being usually larger in size after folding, which is inconvenient to store and transport. Therefore, it is necessary to further improve the frame of the camper in the prior art. Summary of the invention

[0003] The present invention provides a camper frame and a camper with a small folding volume, aiming to solve the problem that the frame of the camper in the prior art can only be folded once, resulting in the camper usually having a large volume after folding, which is inconvenient to store and transport.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] In a first aspect, the present invention provides a camper frame with a small folding volume, comprising four support rods connected end to end to form the camper frame; the camper frame comprises an unfolded state, a first folded state, and a second folded state;

[0006] When the camper frame is in an unfolded state, the four support rods are connected end to end to form a camper frame;

[0007] When the camper frame is in the first folded state, the camper frame is folded in half along a first diagonal line in the unfolded state;

[0008] When the camper frame is in the second folding state, the four support rods are folded and closed together;

[0009] When the camper frame is unfolded, the camper frame is first switched from the second folding state to the first folding state, and then switched from the first folding state to the unfolded state; when the camper frame is folded, the camper frame is first switched from the unfolded state to the first folding state, and then switched from the first folding state to the second folding state.

[0010] A further solution: the four support rods are respectively a first support rod, a second support rod, a third support rod and a fourth support rod from the head end to the tail end;

[0011] A first connecting seat is provided between the first support rod and the fourth support rod, and between the second support rod and the third support rod; a second connecting seat is provided between the first support rod and the second support rod, and between the third support rod and the fourth support rod;

[0012] Each of the first connecting seats includes two sub-connecting seats, each sub-connecting seat is fixedly connected to its corresponding support rod, and the two sub-connecting seats are hinged via a first pin shaft; the first diagonal line is the connecting line between the two first pin shafts.

[0013] Based on the above technical solution: by setting the first connecting seat to include two sub-connecting seats, and the two sub-connecting seats are hinged by a first pin shaft, the line connecting the two first pin shafts forms a first diagonal line, so that when the camping vehicle frame is folded from an unfolded state, it can be folded along the first diagonal line. During the folding process, the two sub-connecting seats rotate relative to each other.

[0014] A further solution: each of the second connecting seats is provided with a fixing portion and a hinged portion;

[0015] The first support rod and the fourth support rod are respectively fixedly connected to their corresponding fixing parts, and the second support rod and the third support rod are respectively hinged to their corresponding hinged parts; or, the first support rod and the fourth support rod are respectively hinged to their corresponding hinged parts, and the second support rod and the third support rod are respectively fixedly connected to their corresponding fixing parts.

[0016] Based on the above technical solution: by setting the second connecting seat with a fixed part and a hinged part and a connection method between the support rod and the corresponding fixed part or the hinged part, after the camper frame is folded along the diagonal, the support rod connected to the hinged part can be rotated toward the support rod connected to the fixed part, so that all the support rods can be folded together, and the volume after folding is smaller.

[0017] A further solution: the fixing portion is a slot, and the support rod connected to the slot is inserted into the corresponding slot;

[0018] The hinged portion is a hinged groove, and the support rod connected to the hinged groove is hinged in the corresponding hinged groove through a hinge shaft.

[0019] Based on the above technical solution: by setting the fixing part as a slot and the hinged part as a hinged slot, the corresponding support rods are easily connected.

[0020] A further solution is that a locking assembly is provided between the two sub-connecting seats for locking the camper frame in the unfolded state when the camper frame is in the unfolded state.

[0021] Based on the above technical solution: by providing a locking assembly, when the camper frame is in the unfolded state, the locking assembly locks the two sub-connecting seats together, so that the camper frame is more stable in the unfolded state.

[0022] A further solution: the locking assembly includes a clamping block arranged on one of the sub-connecting seats and a clamping slot arranged on the other sub-connecting seat;

[0023] When the camper frame is in an unfolded state, the card block is inserted into the card slot; when the camper frame is switched from the unfolded state to the first folded state, the card block is separated from the card slot.

[0024] Based on the above technical solution: by setting a locking component including a card block and a card slot, when folding, the card block can automatically disengage from the card slot as the two sub-connecting seats rotate relative to each other, and when unfolding, the card block can be stuck into the card slot as the two sub-connecting seats rotate relative to each other, thereby achieving automatic locking.

[0025] A further solution: the camper frame is square in the unfolded state.

[0026] A further solution: two of the first connecting seats and two of the second connecting seats are each provided with a column connecting portion.

[0027] Based on the above technical solution: by arranging column connecting parts on both the first connecting seat and the second connecting seat, it is convenient to connect the columns, so that the camping vehicle frame can be used as the base frame of the camping vehicle and can also be used as the side frame of the camping vehicle.

[0028] A further solution: the column connecting portion is a connecting groove.

[0029] In a second aspect, the present invention provides a camper, comprising four upright posts, four sets of wheel assemblies, a push rod assembly, and a camper frame with a small folding volume as described in any one of the schemes in the first aspect;

[0030] The four uprights are located on the upper side of the camper frame, the push rod assembly is located on the front side of the camper frame, and the four sets of wheel assemblies are located on the lower side of the camper frame;

[0031] The push rod assembly, the four upright posts and the four sets of wheel assemblies are all detachably connected to the camper frame.

[0032] Based on the above technical solution: by arranging the push rod assembly, the four columns and the four sets of wheel assemblies to be detachably connected to the camper frame, the push rod assembly, the four columns and the four sets of wheel assemblies can be removed to facilitate the folding of the camper frame.

[0033] The beneficial effects of the present invention are:

[0034] The present invention provides a camper frame including an unfolded state, a first folded state and a second folded state. When folding, the camper frame is first folded in half along a first diagonal line for a first folding, and then four support rods are folded together for a second folding. After the second folding, the camper frame has a smaller volume, occupies less space, and is easy to store.

[0035] By arranging that when the camper frame is unfolded, it is first switched from the second folding state to the first folding state, and then switched from the first folding state to the unfolded state; when the camper frame is folded, it is first switched from the unfolded state to the first folding state, and then switched from the first folding state to the second folding state, it is convenient for users to operate and enable users to fold or unfold the camper frame quickly and orderly.

DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

[0046] Embodiment 1:

[0047] like Figures 1 to 3 As shown, this embodiment provides a camper frame with a small folding volume, comprising four support rods connected end to end to form the camper frame; the camper frame comprises an unfolded state, a first folded state, and a second folded state;

[0048] When the camper frame is in the unfolded state, the four support rods are connected end to end to form a camper frame; the camper frame formed by the four support rods of the camper frame connected end to end can be square in the unfolded state;

[0049] When the camper frame is in the first folding state, the camper frame is folded along the first diagonal line in the unfolded state, and the volume of the camper frame is reduced after being folded along the first diagonal line;

[0050] When the camper frame is in the second folding state, the four support rods are folded together, and after further folding, the volume of the camper frame is further reduced;

[0051] Among them, when the camper frame is unfolded, the camper frame is first switched from the second folding state to the first folding state, and then switched from the first folding state to the unfolded state, that is, when the camper frame is unfolded, it is unfolded in the order of the second folding state to the first folding state and then to the unfolded state; when the camper frame is folded, the camper frame is first switched from the unfolded state to the first folding state, and then switched from the first folding state to the second folding state.

[0052] In some specific embodiments, the four support rods are respectively a first support rod 1, a second support rod 2, a third support rod 3 and a fourth support rod 4 from the head end to the tail end;

[0053] A first connecting seat 5 is provided between the first supporting rod 1 and the fourth supporting rod 4 and between the second supporting rod 2 and the third supporting rod 3; a second connecting seat 6 is provided between the first supporting rod 1 and the second supporting rod 2 and between the third supporting rod 3 and the fourth supporting rod 4;

[0054] Specifically, Figure 4 and Figure 5As shown, each of the first connection seats 5 includes two sub-connection seats 51, each sub-connection seat 51 is fixedly connected to its corresponding support rod, and the two sub-connection seats 51 are hinged through a first pin shaft; when the camper frame is in the unfolded state, the first diagonal line is the line between the two first pin shafts. When the camper frame switches from the unfolded state to the first folded state, the two sub-connection seats 51 can rotate relative to each other, so that the camper frame is folded along the first diagonal line. When the four support rods are of equal length, after folding, the first support rod 1 and the fourth support rod 4 are close together, and the second support rod 2 and the third support rod 3 are close together.

[0055] In order to facilitate the connection between the sub-connection seat 51 and the corresponding support rod, a slot is provided on the sub-connection seat 51, and the corresponding support rod is inserted into the slot.

[0056] In this embodiment, Figures 1 to 3 As shown, in order to facilitate the camper frame to switch from the first folding state to the second folding state, each of the second connecting seats 6 is provided with a fixing portion 61 and a hinge portion 62;

[0057] When the camper frame is in the first folding state, the second support rod 2 and the third support rod 3 can be arranged to rotate toward the first support rod 1 and the fourth support rod 4 so that the four support rods are brought together. Specifically, the first support rod 1 and the fourth support rod 4 are respectively fixedly connected to their corresponding fixing parts 61, and the second support rod 2 and the third support rod 3 are respectively hinged to their corresponding hinge parts 62.

[0058] When the camper frame is in the first folding state, it can also be configured to rotate the first support rod 1 and the fourth support rod 4 toward the second support rod 2 and the third support rod 3 so that the four support rods are brought together. Specifically, the first support rod 1 and the fourth support rod 4 are respectively hinged to their corresponding hinged parts 62, and the second support rod 2 and the third support rod 3 are respectively fixedly connected to their corresponding fixed parts 61.

[0059] In order to facilitate the connection between the support rod and the fixing part 61, the fixing part 61 is a slot, and the support rod connected to the slot is inserted into the corresponding slot, and the connection between the support rod and the slot can also be reinforced by bolts and nuts; the hinge part 62 is a hinge groove, and the support rod connected to the hinge groove is hinged in the corresponding hinge groove through a hinge shaft. For example, when the second support rod 2 and the third support rod 3 are rotated toward the first support rod 1 and the fourth support rod 4 so that the four support rods are close together, the second support rod 2 and the third support rod 3 are respectively hinged to the corresponding hinge groove, and the first support rod 1 and the fourth support rod 4 are respectively connected to the corresponding slot.

[0060] In some specific embodiments, Figure 4 and Figure 5As shown, in order to make the camper frame more stable in the unfolded state, a locking assembly for locking the camper frame in the unfolded state is further provided between the two sub-connection seats 51. When the camper frame is in the unfolded state, the locking assembly locks the two sub-connection seats 51 together to prevent the two sub-connection seats 51 from rotating relative to each other when the camper is subjected to bumps and other factors, so that the camper frame is more stable when in the unfolded state.

[0061] In some specific embodiments, Figure 4 and Figure 5 As shown, in order to facilitate folding or unfolding the camper frame, the locking assembly is preferably a quick-release structure. Specifically, the locking assembly includes a block 52 provided on one of the sub-connection seats 51 and a slot 53 provided on the other sub-connection seat 51; when the camper frame is in the unfolded state, the block 52 is inserted into the slot 53; when the camper frame is switched from the unfolded state to the first folded state, the block 52 is disengaged from the slot 53. When the camper frame is used as the bottom frame of the camper, a specific mode is that the first pin is located on the upper side of the first connection seat 5, and both sub-connection seats 51 are provided with through holes for the pin to pass through. The card block 52 and the card slot 53 are located at the lower side of the first connecting seat 5. The shape of the card block 52 can be set to be a card hook, and the card slot 53 is set to be a shape compatible with the card hook, so that when the camper frame is in the unfolded state, the card hook is synchronously inserted into the card slot 53. When the camper frame switches from the unfolded state to the first folded state, the card hook automatically disengages from the card slot 53 as the two sub-connecting seats 51 rotate relative to each other.

[0062] In some specific embodiments, Figure 1 As shown, when the camper frame is used as the base frame of the camper, in order to facilitate the installation of the column, the two first connecting seats 5 and the two second connecting seats 6 are both provided with a column connecting portion. Specifically, the column connecting portion can be a connecting groove 7.

[0063] Embodiment 2:

[0065] The four uprights 8 are located on the upper side of the camper frame, the push rod assembly 10 is located on the front side of the camper frame, and the four sets of wheel assemblies 9 are located on the lower side of the camper frame;

[0066] The push rod assembly 10, the four upright posts 8 and the four sets of wheel assemblies 9 are all detachably connected to the camper frame.

[0067] Specifically, the first connection seat 5 and the second connection seat 6 are both provided with connection grooves 7, and the four pillars 8 of the camper are respectively inserted into the four connection grooves 7. The bottom of the connection groove 7 is provided with a through hole, and the upper end of the wheel assembly 9 is inserted into the through hole so as to be detachably connected with the pillar 8, which can be specifically connected in a clamping manner. The first connection seat 5 and the second connection seat 6 located on the front side of the camper frame are both provided with a push rod hinge seat, and the left and right sides of the lower end of the push rod assembly 10 are respectively hinged with the first connection seat 5 and the second connection seat 6 located on the front side, and the push rod assembly 10 and the camper frame can be set as a quick-release structure to facilitate disassembly, such as by bolts and nuts. The camper can also be provided with a storage cloth 11, and specifically, the storage cloth 11 is connected to the four pillars 8.

[0068] When the camper is folded, the push rod assembly 10, the four sets of wheel assemblies 9 and the four uprights 8 are first removed, and then the frame of the camper is folded.

[0069] Working principle description:

[0070] When the camper frame is folded, the camper frame is first folded along the first diagonal line, and then the second support rod 2 and the third support rod 3 are rotated toward the first support rod 1 and the fourth support rod 4, so that the four support rods are folded and put together. When the camper frame is unfolded, the second support rod 2 and the third support rod 3 are first rotated away from the first support rod 1 and the fourth support rod 4, so that the camper frame is switched to the first folded state, and then rotated along the first diagonal line, so that the camper frame is switched to the unfolded state.
